SLICING-MACHINEa SPECIFICATION forming part of Letters Patent No. 519,959, dated May 15, 1894.

Application iled (l'une 27| 1893. Serial No. 478.986. (No model.)

To @ZZ whom it may ooncerm Be it known that we, ANTHONY ISKE and ALBERT IsKE, citizens of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in slicing-Machines; and we do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in that class of slicing machines which are especially adapted to the slicing or chipping of dried-beef, bologna-sausage, radishes, potatoes, and the like; and in which the cutting is done by an inclined knife-blade rigidly secured in position reciprocating motion, back and forth, in guide grooves formed in parallel strips or rails se-l cured to the framework of the machine.

The object of the invention is to provide a hinged plate or gate, in front of the knifeblade, and a setscrew,'swiveled, whereby the free edge of said gate may be moved towardV or from the cutting edge of the knife, to regulate the thickness of the cut or chip, more sensitively, conveniently and quickly than can be done in slicers of this class as they have heretofore been constructed.

The particular features of the invention will more clearly appear in the following description, and will be distinctly set forth in the claims.

The purposes of the invention are attained by the mechanism and devices illustrated in the accompanying drawings, in which similar letters and figures of reference designate like parts throughout the several views, and in which--n Figures 1, 2 and 3 are, respectively, a plan, a front and an end elevation of a slicing machine embodying the elements of the invention. Fig. l is a plan of the central portion below the line @s so, viewed from the direction of the arrow 1 in Fig. 2; Fig. 5, an end view of the portion of the reciprocating knife-rack to the left of the line y y, viewed from the direction of the arrow 2, in Fig. 2. Figs. 6, 7, 8 and 9 are views showing details in the construction.

to a vertical plate having aV In the drawings A designates the sliding or knife supporting rack which is preferably made of cast iron in one body, practically rectangular in form. It consists of top and bottom rails A and A2, each provided along its inner edge with a projecting rib a, which ribs are oppositely disposed and adapted to move back and forth in guide-grooves yet to be described. These rails are joined by two plates A3 and A4 set in separate parallel vertical planes, so as to be off-set with each other, best shown in Figs. 4. and 5, which off-set should always be equal to the depth of the thickest chip it is desired to cut; and the plates have an oblique opening A5 between them,

best shown in Fig. 2, against the oblique sides" of which are secured the cutting knife and gaging plate both to behereinafter described and this gaging plateis a distinctive feature of the present invention. The plates are provided on, the outside with strengthening ribs a' and a wide strip a2, is placed along the oblique edge of the plate A3 to better support the said cutting blade, while the'top and bottom rails are also joined by vertical end ribs as, flush with their outer edges, and the guiderib a of the bottom rail is provided near its left hand end with a notch a4 to be engaged by a locking plate yet to be described. Into the back of the wide strip a2, is formed a recess 0,5, into which is placed the knife or cutting blade 3 and, by means of screws 4 tapped into said strip, it is rigidly secured to said plate, see Figs. 2, 4 and 5. In front of the knife, and filling the rest of the opening A5, is fitted a plate or adjusting gate A, provided along its top and bottom and forward oblique edges with outwardly projecting ribs as to strengthen said gate, while its oblique` hinged to the oblique forward" rear edge is edge of the plate A4. This gate is also provided on its ont-er face with a rearwardly proj ecting arm A7 having tapped through itsfree end a thumb or finger screw A8 which has its extremity a7 loosely swiveled into said plate A4, whereby said gate may be readily adj usted to regulate or gage the thickness 'of the cut, see Figs. 2 and 4, but it is best shown in Fig. 5.' The outer face of the plate A5, near the left hand end of the rack A, is provided with a handle A9, to reciprocate said rack; said IOO handle, by means of a pin a8, being pivoted to said plate so as to oscillate with the motion of the actuating hand.

To support the knife-rack in working position a metallic frame Bis provided, which may be integrally made as one casting, and it consists of two horizontal rails, an upper one B and a lower one B2, joined near their extremities by vertical posts B3 and B4.` The lower rail, within a recess, is secured verticallyin place by screws Z2 to the forward face of a wooden base 5. Along the forward edges of these rails, Vand oppositely disposed, are formed angular recesses Z2', Figs. 3, 8 and 9, having a depth a trifle greater than the width vof the top and bottom rail-ribs a before described, forming a portion of the guide grooves to engage said ribs, while strips or plates B5 .and B6, secured in place against said edges, by screws b2, serve to complete said groove. These plates are provided along their opposing edges with outwardly projecting flanges b3, forming bearing faces against which the top and bottom rails of the knife-rack ride. The orifices through which the screws b2 pass are made vertically oblong, (shown in Fig. 2,) so that said plates may be raised or lowered at pleasure t0 take up any lost motion that may occur between said rack and plates. The upper plate is providedlwith an ornamental center piece 'b4 which may serve as a nameplate. Rearward of `the post B4, having its inner face in line with the inner face of said post, is pivoted the forward end or edge of a door orgate B7, by means of trunnions or pivot pins b5,which.project upward and downward from said end, the upper one passing through, extending slightly beyond, an orifice in a rearwardly projecting lug from the topral, B', of the frame, and the lower one, into an orifice or socket formed in the upper face of thewooden base,5. Near the rear end of the gate, and projecting outward from the lower edge of its outer face, is a two-pronged lug or jaw h6 to engage a vertically disposed screw and to receive the action Yof a thumb-nut t0 hold'saidgate fixed in opened position. This gate, extended rearward and tixed in position, Fig. 1, forms a rest for the articles to be chipped or sliced; and it may be folded forward against the supporting frame as is shown by dotted lines 57 in Fig. 4C.

Extending horizontally rearward from the wooden base, 5, its upper face being level therewith, is an approved platformC, having its forward edge hinged, as at c, to the top of said base. Near the upper right hand corner of the platform is fixed an upwardly projecting screw C to engage the lug be, before mentioned, and a thumb-nut c', screwed home thereon, serves to secure said gate and platform together. Pivoted centrally to the rear edge of the platform by a screw 6, i s a strip C2, having in its inner face, near the lower edge and left hand end, a vprolonged and outwardly sloping recess c2, shown by dotted lines in Figs. l, 3 and 4f, and by full lines in Fig. 7. The platform, C, forms the base on which the articles to be cut or chipped are placed, and it may be folded upward against the topof the supporting frame; the strip, C2, supports the rear end of said platform in a level position, and on being reversed on its pivot screw 6, the recess c2 is brought into position to receive the projecting end of the upper trunnion, b5, to hold the folded platform in position, as indicated by dotted linescg, all of which is best shown in Fig. 3.

Against the left hand end of the wooden base, 5, is rotatably secured a metallic plate D by vmeans of a screw d, the plate consisting of a straight portion D provided with an outwardly projecting handle d near one end, and a curved portion D2 so placed as to form a notch or angular stop d2, at the other end thereof, the pivot or rotating point being eccentric of said curved portion. A pin Z3 is placed in this end of the base, as shown, to stop the upward progress of the plate when it is turned in this direction. When the plate, D, occupies the position'shown in Figs. l, 2 and 3, it forms a stop against the edge of a table or board, to hold'the machineinplace while in use for slicing or chipping; and when it occupies the position shown in Fig. 6, the curved portion, D2, having entered the recess, a4, (Fig. 2,) and the stop d2 having been brought against the knife-rack, said blade serves to securely lock said knife-rack, preventing it from being reciprocated in its guides.
